An example of an exception to the NSUs is where a turbine is located in an area that cannot be accessed without crossing an ephemeral stream. Ifit is determined that the stream is a Water of the U.S., then a Section 404 permit will be obtained thereby allowing an access road to be constructed. Another example is the slope criteria. The accuracy of the digital terrain model used for this analysis is insufficient formicro-siting. Engineering judgment was used to determine in a limited number of cases that it may be possible to grade a resource road to design criteria.”See Chapter 8.0, Glossary.Per the PCW Response and Data on BLM Alternatives (December 2009) footnotes to Alternatives Summaries #10, “seasonal timing restrictions were not applied to construction activities on private land.”Volume IIJune 2012
